Javax.mail.AuthenticationFailedException

Question

我试图使用Gmail smtp服务器从我的应用程序发送电子邮件。为此，我使用了javax库。

MailSender.java

public class MailSender { 

final String emailPort = "587";// gmail's smtp port for tls 
final String smtpAuth = "true"; 
final String starttls = "true"; 
final String emailHost = "smtp.gmail.com"; 

String fromEmail; 
String fromPassword; 
String toEmail; 
String emailSubject; 
String emailBody; 

Properties emailProperties; 
Session mailSession; 
MimeMessage emailMessage; 

public MailSender() { 

} 

public MailSender(String fromEmail, String fromPassword, String toEmail, String emailSubject, String emailBody) { 
    this.fromEmail = fromEmail; 
    this.fromPassword = fromPassword; 
    this.toEmail = toEmail; 
    this.emailSubject = emailSubject; 
    this.emailBody = emailBody; 

    emailProperties = System.getProperties(); 
    emailProperties.put("mail.smtp.port", emailPort); 
    emailProperties.put("mail.smtp.auth", smtpAuth); 
    emailProperties.put("mail.smtp.starttls.enable", starttls); 

    Log.i("MAIL_SENDER", "Mail server properties set."); 
} 

public MimeMessage createEmailMessage() throws AddressException, MessagingException, UnsupportedEncodingException { 

    mailSession = Session.getInstance(emailProperties, new javax.mail.Authenticator() { 
     @Override 
     protected PasswordAuthentication getPasswordAuthentication() { 
      return new PasswordAuthentication(fromEmail, fromPassword); 
     } 
    }); 
    emailMessage = new MimeMessage(mailSession); 

    emailMessage.setFrom(new InternetAddress(fromEmail, fromEmail)); 
    emailMessage.addRecipient(Message.RecipientType.TO, new InternetAddress(toEmail)); 
    emailMessage.setSubject(emailSubject); 
    //emailMessage.setContent(emailBody, "text/html");// for a html email 
    emailMessage.setText(emailBody);// for a text email 

    Log.i("MAIL_SENDER", "Email Message created."); 

    return emailMessage; 
} 

public void sendMail() throws AddressException, MessagingException { 

    Transport transport = mailSession.getTransport("smtp"); 
    transport.connect(emailHost, fromEmail, fromPassword); 
    transport.sendMessage(emailMessage, emailMessage.getAllRecipients()); 
    transport.close(); 

    Log.i("MAIL_SENDER", "Email sent successfully."); 
} 

}

这是怎么了，我从活动/服务发送电子邮件：

private void sendEmail(String email) throws Exception{ 
    String from = "myemail@gmail.com"; 
    String pass = "mypass"; 
    String to = email; 
    String subject = getString(R.string.email_subject); 
    String body = location_link; 

    sendMailTask task = new sendMailTask(); 
    task.execute(from, pass, to, subject, body); 
} 

private class sendMailTask extends AsyncTask<Object, Object, Object> { 

    @Override 
    protected Object doInBackground(Object... args) { 
     try { 
      MailSender mail = new MailSender(args[0].toString(), 
        args[1].toString(), args[2].toString(), args[3].toString(), 
        args[4].toString()); 
      mail.createEmailMessage(); 
      mail.sendMail(); 
     }catch (Exception e) { 
      Log.e("EMAIL", e.getMessage(), e); 
     } 
     return null; 
    } 
} 

但每次它调用瞬移（）方法中，我得到LogCat中的此错误：

它与autentification有关。事实上，我收到来自我帐户中的谷歌电子邮件，告诉有人试图访问我的帐户...

下面的代码工作正常。为此，您需要从http://code.google.com/p/javamail-android/downloads/list链接下载libarary，并从https://commons.apache.org/proper/commons-email/download_email.cgi链接下载commons-email。删除所有其他的java邮件库只添加这四个库;

import org.apache.commons.mail.DefaultAuthenticator; 
import org.apache.commons.mail.Email; 
import org.apache.commons.mail.EmailException; 
import org.apache.commons.mail.SimpleEmail; 

private class MailClass extends AsyncTask<String, Void, Void>{ 

     @Override 
     protected Void doInBackground(String... params) { 
      try { 
       Email email = new SimpleEmail(); 
       email.setHostName("smtp.googlemail.com"); 
       email.setSmtpPort(465); 
       email.setAuthenticator(new DefaultAuthenticator("abc@gmail.com", "abc_password")); 
       email.setSSLOnConnect(true); 
       email.setFrom("abc@gmail.com"); 
       email.setSubject("TestMail"); 
       email.setMsg("This is a test mail ... :-)"); 
       email.addTo("dhavalpatel.244@gmail.com"); 
       email.send(); 
      } catch (EmailException e) { 
       e.printStackTrace(); 
      } 

      return null; 
     } 

    }
